COMBINED WINDQW'AND VENTILATOR I Filed July 14, 1928 www A vTTORNJE Y Patented Sept, El), 193@ TATES PATENT FFHQE COMBINED 'WINDOXV AND VENTILATOR Application filed July 14,

rlhis invention relates to improvements in windows and has particular reference to a combined window and ventilator.

ln my United States Patent No. 1,608,090, issued November 23, 1926, there is shown a ventilator adapted for use in connection with the usual construction of windows having two sashes and includes a screened frame mounted in juxtaposition to the lower sasii ot a window by means of triangular end brackets and having,` louvres for regulating' theamount of air entering a room through the screen in said Jframe.

In accordance with the present invention it is proposed to adapt this general type of ventilator to windows of various constructions, such as the Casement type, and to mount the ventilator in position in a simple and effective manner so that it will, for all practical purposes, constitute a part of the window and, at the same time, be capable of adjustment to regulate the ventilation of a room when the window is closed. The conception herein involved is also applicable in its principles to what are known as double hung windows, in which case the ventilator portion occupies either all or part of one or both ot the sashes, and also applies to center pivoted Windows in which the latter may be swung about horizontal or vertical axes.

The inventive idea involved is capable of receiving a variety of mechanical expressions, some of which, for purposes of illustrating` the invention, are shown in the accompanying' drawing; wherein- Figure l is a perspective View of a coinbined easement window and ventilator coustructed in accordance with the invention Figure 2 is an enlarged tra ginentary vertical section;

Figure 3 a Jtrap mentary top plan view` partly broken away and shown in section i Figure el is a fragmentary perspective view ci one ot the end brackets forming` a part of the ventilator; and

Figure 5 is a view similar to Figure 2, showing' a slightly different form of mounting for the ventilator.

Although the invention is shown and described in connection with what is generally 19.28. Serial No. 292,694.

known as a easement window, it is not to be construed as limited in its adaptation to this type and may be employed with other kinds of windows such as previously mentioned. In the drawing, indicates a Casement window sash which, in Figure 1, is of the type which swings inwardly and has its upper portion above the ventilator divided to receive a number of small panes oit glass, the lower edge of said portion being formed by the horizontal sash bar 11. lt is to be understood that the construction shown herein is not limited in its application to in-swinging casements nor to sashes which contain a number of small panes of glass for, as will be seen in Figure 5 which will later be described in detail, the structure may be incorporated with a easement having` only a single large pane.

The ventilator forming a part of the casement is shown as comprising a pair oi complemental end brackets 12 each of substantially triangular shape and provided upon its forward or inclined edge with an inturned flange 13 terminating short of the upper end olf the bracket and against which one end ot the pane of glass 14ris adapted to rest with the lower edge of the glass engaging the lower ruil 15 of the easement sash and secured thereto by putty 16 or other suitable means. The rear or vertical edge of each bracket is provided with an outturned fiange 17 also terminating' short of the upper end of the braclret and adapted to engage the outer surface oi the adjacent vertical stile 17 of the sash and bc secured tl vreto by suitable JEastencrs 1S whereby to aiiix the bracket in position` The ventilator further includes the traine 19 having the screen 20 covering its opening. Said trame is mounted in a horizontal position between the upper ends oi the brackets 12, in a manner to presently appear, and has secured to the lower edges of the longitudinal sides thereof the opposed angular supportingl strips 21. The vertical portions of said strips extend upwardly into the Jframe in spaced relation to said sides. and form bearings for the trunnions 22 of a plurality or" louvres 23 arranged transversely of the trame beneath theopening therein and constituting a shutter device by means of which the admission of air through the ventilator may be eon trolled. The various louvres are interconnected by a rod 24k and one oit the trunnions el.

...y a louvre extended through the 'front longitudinal side of the frame. l) and prov' :l with a handle or knob 25 Aby ineens o? which the leurres niay be adjusted to opened, closed or intermediate positions.

For the purpose of mounting the traine l5) in position, each bracket l2 provided along its upper edge with an inturned flange Q5 adapted to engage the upper suritaee or the adjacent end of the ranie. The distance hetween said flange Q6 and the upper end et fiange 13 is equal to the thickness ot' the traine so that the lower surface ot the latter will rest upon and be partially supported hy said end of the flange 13. To -tuither secure the frame in place, the vfoiward portion of each bracket adjacent its upper end is itornied with an opening 27 for receiving a. screw or other fastener which is driven into the end of the frame. As a. further securing ineens for the frame, there is provided the niet-al strip 28 extending the length of the back or outer longitudinal side of said traine and secured thereto by screws :29. The strip is greater in width than the thickness of the frame and is bent longitudinally to provide the angular portion 30. Said portion extends. along the lower angle in the cross har 1l and after first inserting putty 3l in the space between said portion and corner et the angle, the strip is attached to the bar Il by the screws 32. Finally, a quantity ot putty is inserted along the upper edge of the pane 14 and the lower surface of the iront strip 21 to seal the space therebetween. Thus.y the ventilator is securely mounted in and made a part of the easement sash.

Figure 5 illustrates the adaptation et the inventive idea to a. ement having but a single pane of glass Set. The eonstruetion of the ventilator is precisely the saine as that previousl;Y desrrihed7 but in order to inount the same between the lower edge oit the pane 34 and the bottoni oi.E the sash, a different forni of securing strip from he strip 2h is used. Thus, a. strip is lient to provide ria angular portions 35 aud 3G and folded upon itself, as indicated at 537. to torni a r` -e against which the pane 3i ahnte4 when a seated upon the portion 35 and` sew y on by putty 38. The portion Se to the rear edge of the train,

lVhat is claimed is:

sash having an opening therein, a 'vent' mounted in said opening and iueluding a frame extending inwardly from the upper edge of said opening, end brackets in wlnr. said frame is supported and having llana c: fornied along one edge for attachment to the vertlcal Stiles 0f said sash, andan angulL r fastening strip having one portion extend ing along and seeurvd to one side oi' said trarne and its other portion fastened to the part of the sash forming said upper edge.

In testimony whereof I have atlixed my signature.
